The 2012 Jaguar XF has been officially unveiled at the New York Auto Show. It features revised styling, an upgraded interior, and a new diesel engine.

There's a Jaguar on the loose as the British brand has unveiled the 2012 XF at the New York Auto Show.

Drawing inspiration from the XJ, the updated model features a new front fascia which incorporates a revised grille and bi-xenon headlights with integrated LED daytime running lights. Elsewhere, there's a new hood, modified front fenders and redesigned LED taillights.

Inside, the changes are less obvious but include improved seats, revised switchgear, a digital instrument cluster, and a new infotainment system with a seven-inch touchscreen display.

Engine options apparently carryover with the exception of a new 2.2-liter four-cylinder diesel that produces 190 PS (140 kW / 187 hp) and 450 Nm (332 lb-ft) of torque. It is connected to an eight-speed automatic transmission which enables the car to accelerate from 0-100 km/h in 8.5 seconds, hit a top speed of 225 km/h (140 mph), and average 52.3 mpg UK (5.4 L/100km / 43.5 mpg US) with CO2 emissions of 149 g/km.
